E-Readers are portable electronic devices designed primarily for reading digital books and publications. They use E-ink technology, which mimics the appearance of ink on paper, providing a comfortable reading experience without the glare of traditional screens. These devices often come with features such as adjustable font sizes, built-in dictionaries, and the ability to store thousands of books. Popular models include the Amazon Kindle and Kobo Clara, making reading more accessible and convenient for users on the go.
